Can't remove Service pack 1, v.658 :-(

I'm Running Vista Ultimate and I'd like to install Service pack 1, v.668
but I can't remove the "old" Service pack 1, v.658 that I have already
installed.

When I try to remove it from "Installed Updated" it start removing it but
after a few
minutes I get the following message : "an error has occurred, not all the
updated
were successfully uninstalled".

I'll appreciate any help..
George.

Here is a public newsgroup that you can ask for help. I can tell you that
you will not be able to install SP1 RTM untill the Beta builds are removed.
